Drawings from IBM Floppy Disk Drive Patents. IBM's decision in the late 1960s to use semiconductor memory as the writeable control store for future systems and control units created a requirement for an inexpensive and reliable read only device and associated medium to store and ship the control store's microprogram and at system power on to load the microprogram into the control store.
A floppy disk or floppy diskette (casually referred to as a floppy, a diskette, or a disk) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk.
Upon the basis of the Juusyoku Record patent issued in 1952, Nakamatsu claims to have invented the first floppy disk [3] well before IBM's floppy disk patent was filed in 1969. [26] However, what Nakamatsu patented in 1952 was a paper for optical sound player. [ 12 ]

A Maxell-branded 3-inch Compact Floppy Disk. The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. [1] Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and ...
STORY: (Tim Persky, Floppy disk seller)"If you think this is old, take a look at this. This is a floppy disk from the 1970s."This man is believed to be the world's last known bulk supplier of ...
The fixed disk has 10,618,880 bytes [G] of raw space. The DOS partition on the fixed disk continues to use the FAT12 format, but with adaptations to support the much larger size of the fixed disk partition compared to floppy disks. Space in the user data area of the disk is allocated in clusters which are fixed at 8 sectors each.
Examples include the very tiny handle on maple syrup bottles, faux buckles on shoes, the floppy disk 'save' icon, or the sound of a shutter on a cell phone camera.
